Hit Tracker "determines the true distance a home run travels by recreating the precise trajectory the ball followed during flight, and extending that trajectory all the way back to field level to allow 'measurement' of the home run." Hit Tracker's spreadsheet tool takes inputs that include atmospheric information, and outputs "the true distance that the home run traveled, along with the initial speed of the hit off the bat and the precise angles at which the ball left the bat." See leaderboards of home runs based on true distance and speed off bat; listings of "no doubts," "just enoughs," and "lucky homers"; and scatter plots of every round tripper hit by a Major League Baseball batter or conceded by a pitcher. The table of current season home runs links to game video; and allows sorting by date, inning, or alphabetically by name of hitter, pitcher, or ballpark. The "Highlight Homers" section provides in-depth examination of "notable home runs from the past and present, particularly long ones." See also the Hit Tracker Blog.
